Honeywell Home smart thermostat gains a room sensor at CES 2019

Resideo's Honeywell Home T9 Smart Thermostat comes with one temperature, humidity and motion sensor.


The T9 Smart Thermostat costs $200 and your purchase includes one remote room sensor.


Resideo has a new Wi-Fi smart thermostat, the $200 Honeywell Home T9.

Unlike previous Honeywell Home thermostats such as the Lyric and the Lyric T5, the T9 includes a room sensor designed to detect temperature, humidity and motion. But that sensor can't be paired with previous Honeywell Home thermostats -- it will only work with the T9. Set it in any room you want to regulate more closely. Each room sensor runs on two AAA batteries and Resideo claims they have a 200-foot range. 

Both Ecobee and Nest already sell temperature sensors that work with their smart thermostats.

The T9 will be available in the spring. Additional room sensors will be sold in packs of two for $80. It will work with Alexa and Google Assistant at launch as well.

A "pro" version of Resideo's new thermostat, called the T10, can be purchased through dealers and will include "humidity and ventilation controls."
